Older generations of Energy Saving Devices (ESD) can be activated with any business or other plastic loyalty cards. The Energy Saving Devices supplied by KAS are activated using our KAS supplied guest cards only, which significantly increases the gained savings from this unique device.
When guests insert a keycard into the energy switch, the main power supply is turned on. The lighting system, TV and sockets are then activated.
The switch will only be activated by KAS system Guest Cards and not other business or plastic loyalty cards.
The A/C is turned off when a window/door is opened to conserve power. It is re-activated when the window/door is closed again.
When guests remove their card as they leave, all power is switched off after a 30 second egress time.
The Energy Saving Device (ESD-950) has two relay switches. The first relay will power up the lights and room power while the Guest Card is installed inside the reader. The second relay will only allow the air conditioning system to operate if the Guest Card is inserted and the windows and/or doors are fully closed. This is achieved by installing a reed switch on the doors and windows.
Upon vacating the room and taking your Guest Card with you, all the ‘mains’ power and air conditioning systems will be switched off.
